Hi,
an implementation of IExitConfirmation is used to customize the dialog
message when you try to navigate away from your application or close the
browser. There is no sense to trigger this dialog from your application
UI. Please note that the "exit confirmation" dialog and its message are
not respected in all browsers. See:
